Abstract
A method for providing a multicast and broadcast service (MBS) by transmitting a plurality of data frames in a wireless network. The method includes: generating a first MBS data information element (MBS-DATA-IE) in a first one of the data frames, the first MBS-DATA-IE including information relating to a logical channel of the MBS, and indicating a location of an MBS map (MBS-MAP) in a second one of the data frames; determining ones of the data frames between the first and second ones of the data frames in which to add a plurality of extra MBS-DATA-IEs; and generating the extra MBS-DATA-IEs, the extra MBS-DATA-IEs being generated in the determined ones of the data frames and including information relating to the logical channel.
